Hitching is possible in Laos, if not common, though it's never entirely safe and not rec­ommended for women as the act of stand­ing beside a road and waving at cars might be misinterpreted. If you are hitching, cars with red-on-yellow (private vehicle) or blue-on-white (international organisations and embassies) number plates might be the best ones to target. Long-distance cargo trucks are also a good bet.
